LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 403,657, dated May 21,1889.

Application filed February 18, 1889. $e1'ial No. 300,225. (No model.)

To all whom it may concern.-

Be it known that I, JOHN B. GLOVER, of Dubuque, in the county of Dubuqueand State of Iowa, have invented a certain new and useful Improvement inLubricating Devices, of which I declare the following to be a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

This invention is in the nature of an improvement in devices forlubricating journals, &c.; and the invention consists of a lubricatingdevice with its several parts arranged, constructed, and combined in themanner hereinafter particularly sho wn, described, and claimed.

In the accompanying sheet of drawings, Figure 1 represents the deviceapplied to a piece of machinery. Fig. 2 is a vertical section of the cupand view of its interior. Fig. 3 is a vertical section at right anglesto the plane of Fig.

Similar letters of reference indicate like parts in the several views.

The thing to be desired in lubricating journals, &c., is to keep thesurfaces sufficiently and certainly oiled without wasting oil byflooding them or allowing the journals to get heated by an insufficientor uncertain supply of oil. The devices contrived to bring about thisobject are almost without number; but it is believed that my device issimpler, less expensive, and more positive in its action than any other,and possesses the additional advantage of ready application to theordinary oil-cup.

Inside the ordinary oil-cup, A, is fixed a tube, B, open at both ends,and of any convenient length. To the upper part of this tube is screwedor in some way fixed a tubesection, 0, the interior of which correspondsto the exterior of the tube B. It is obvious that this section, insteadof being separate, may be an enlargement of the tube B. In

the section C are cut slots to and b, opposite section 0 by a wire, 6,that is bent practically at a right angle, forming an arm, f, to whichis adj ustably secured a weight, 9. Then the sphere is in this waypivoted to the section 0, its diameter should be such as to cause thesphere practically to close the upper end of the tube B in the samemanner as would a ball-valve, and when the tube B is so closed by thesphere, though the oil-cup 1s filled with oil, no oil is admitted intothetube; but when the oil-cup is fixed to machinery having a rotating oroscillating motion then the motion of the machinery causes the welght gto swing as a pendulum, and by so dolng brings the channels 0 and (Z andthe part ot the sphere which is not channeled alternately opposite thelower parts of the slots (1, and b, so that when the channels in thesphere are opposite these slots the oil in the cup can percolate throughthem and through the tube B to the journal, and when that part of thesphere without the channels is opposlte the slots a and b in the sectionC then the oil is shut off from the mouth of the tube B, and so on thesupply is continued and denied access to the journal. 7.

The rapidity with which the oil may be tied to the journal may beregulated by moving the weight 9 up or down on thearm,as in anypendulum.

It will be seen from the foregoing construction that the supply of oilto a journal by my device is certain and not liable to gummin g orclogging; but as long as there 1s Oll in the oil-cup it will surely findits way to the journal that is intended to be lubricated by it.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A lubricating-cup provided with an in terior tube extending upwardfrom the bottom of the cup, and a channeled sphere provided with apendulum pivoted in the upper end of said tube, substantially as and forthe purpose described.

2. In combination, an oil-cup fitted with a tube, B, with anenlargement, C, at its upper end, having slots a and b, a sphere, I),with channels. 0 and d, formed therein pivoted to said enlargement,and-an arm with a ball, g, fixed thereto, whereby said sphere is made tooscillate and alternately admit and shut off the oil within the cup toand from the tube 13, as and for the purpose described.
